[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] like Figure 1 As shown, the utility model provides a hollow thin-walled heat dissipation cold plate with water inlet and outlet on one side, comprising a base plate 1, a partition plate 2, a water inlet 3, and a water outlet 4, wherein:

[0029] The substrate 1 is a hollow thin-walled structure with a heat dissipation cavity formed inside;

[0030] The partition plate 2 is horizontally arranged in the heat dissipation cavity of the base plate 1 to separate the entire heat dissipation cavity into two independent upper and lower parts;

[0031] There is a gap between the end of the partition plate 2 and the rear wall of the heat dissipation cavity to form a reflux return port 5;

[0032] The water inlet 3 and the water outlet 4 are arranged one above the other and are connected to the upper and lower heat dissipation chambers respectively.

[0033] Through this structural setting, while achieving water cooling, it can also achieve single-sided water inlet and outlet, which is convenient for the structural processing of the heat dissipation cold plate. The single-sided water inlet and outlet has a simple structure and there is no problem of waste of raw materials during processing. Compared with the structure with water inlet on one side and water outlet on the other side, the heat dissipation cold plate with single-sided water inlet and outlet is small in size due to the structural connection that takes up space. Under the premise of achieving the same performance of the shell, compared with the water outlet structure on both sides, the structural lightweight level is higher, and this structure can also withstand high pressure.

[0034] As a further improvement of the utility model, Figure 2 As shown, there are several substrates 1 which are arranged side by side.

[0035] Of course, the structure of each substrate 1 is the same as the structure described above, and each substrate 1 has a partition 2, which can form a single-side water inlet and outlet structure. Since the structures are exactly the same, they will not be described in detail here.

[0036] like Figure 2 As shown, in order to facilitate the inlet and outlet of water, a confluence frame 6 is also included which is arranged on one side of the water inlet 3 of the substrate 1 .

[0037] By providing the confluence frame 6, the incoming water can be evenly distributed to the water inlet 3, and all the outgoing water can be confluent together for discharge.

[0038] As a further improvement of the utility model, the confluence frame 6 is a long hollow structure with partitions 7 arranged inside to form an upper confluence chamber and a lower confluence chamber; the upper confluence chamber is connected to all the water inlets 3; the lower confluence chamber is connected to all the water outlets 4; or, the upper confluence chamber is connected to all the water outlets 4; the lower confluence chamber is connected to all the water inlets 3; a first through hole 8 is arranged at one end of the confluence frame 6 corresponding to the position of the upper confluence chamber; a second through hole 9 is arranged at the other end of the confluence frame 6 corresponding to the position of the lower confluence chamber.

[0039] like Figure 2 As shown, the following is a specific description taking an embodiment as an example. In this embodiment, the water inlet 3 is located at the upper part of the substrate 1, that is, connected to the upper heat dissipation cavity, and the water outlet 4 is located at the lower part and connected to the lower heat dissipation cavity; of course, the positions of the two can also be interchanged, which will not be repeated here.

[0040] As an optional implementation of the present utility model, the water inlet 3 is a long strip opening, extending along the height direction of the base plate 1 .

[0041] As an optional implementation of the present utility model, the water outlet 4 is a long strip opening, extending along the height direction of the base plate 1 .

[0042] Of course, the water inlet 3 and the water outlet 4 can also be respectively set to other shapes, such as circular, trapezoidal, etc., which are not specifically limited here.

[0043] Further, such as Figure 1 As shown, in this embodiment, the base plate 1 is in a T-shaped structure as a whole, including an extension section and a main body section, and the water inlet 3 and the water outlet 4 are both arranged in the extension section.

[0044] The heat dissipation cold plate with single-side water inlet and outlet provided by the utility model is a water-cooled heat dissipation cold plate, which uses a circulating cooling medium to perform heat exchange and heat dissipation. Compared with air-cooled and solid heat dissipation plates, it has a better heat dissipation effect. By arranging the water inlet 3 and the water outlet 4 on one side of the heat dissipation cold plate, single-side water inlet and outlet are achieved, the structure is simple, and while achieving the same performance, the volume is smaller, the cost is lower, and the structure has a higher level of lightweight.

[0045] In this embodiment, the overall thickness of the heat dissipation cold plate is 2-2.4 mm, while the wall thickness of the heat dissipation cold plate is only 0.3-0.7 mm. In this embodiment, the heat dissipation cold plate is integrally formed of stainless steel metal material.

[0046] Furthermore, the heat dissipation cold plate of the utility model is made of metal material, formed by plastic mold, and then fixed by high temperature. The key points are: 1. The raw material of the product formed by plastic mold can only be plastic particles, and we improve the structure of the plastic mold, use the modified metal material as the raw material for product molding, and then carry out the molding by the melting point suitable for this modified metal material.
